One of the most powerful tools of nature conservation in the 21st century is our ability to put the protection of Canadian species into a global context. By documenting Canadian species that are not just rare in Canada, but rare everywhere, we can better understand the role of Canadian conservation efforts in preventing global species extinctions.

Those monarchs travel thousands of kilometres, many from summer breeding grounds in Canada that once stretched from southern Saskatchewan to the Maritimes. As a child growing up in southwestern Ontario, I collected insects. Monarchs were abundant everywhere. The mass exodus through Point Pelee at summer's end was mesmerizing.

About four million Canadians -- including more than a million children -- lack food security, defined as reliable access to a sufficient quantity of affordable, nutritious food. Sadly, it's not just humans who are affected by mismanagement of food systems and the ecosystems of which they are a part. Wildlife feel the impacts as well.
Three years ago, the eastern monarch butterfly population plummeted to 35 million, a drop of more than 95 per cent since the 1990s. More than a billion milkweed plants, which monarchs depend on for survival, had been lost throughout the butterfly's migratory range -- from overwintering sites in Mexico to summer habitat in Canada. A lot has changed in three years, but there's still more work to do if we're to save the ailing monarch population.

The good news is that citizen scientists and backyard butterfly lovers from across the northeastern U.S. and southern Canada have reported through social media that monarch butterflies are arriving and laying a remarkable number of eggs. But it's too early to gauge whether the numbers will meet already low expectations.

In the mid-1990s, the eastern monarch population was more than one billion. In winter 2013, the population had dropped by more than 95 per cent to 35 million, with a modest increase to 56.5 million this past winter. Much of the monarch butterfly decline has been pinned on the virtual eradication of its critical food source milkweed.

The dramatic decline in the monarch butterfly population in Eastern North America is due largely to the steady loss of milkweed crops in U.S. breeding grounds, according to a new study that researcher...
Monarch butterflies are in trouble, their numbers drastically reduced. Experts and others are calling on citizen scientists -- and politicians -- to help. We can only hope our leaders live up to their commitment,. But we can also become citizen scientists to help monarchs survive.

What weighs less than a paperclip, tastes terrible and can travel thousands of kilometres without a map? Hint: this delicate critter is tawny-orange with black veins and white spots and has been mysteriously absent from Canada this summer.
Monarch butterflies appear headed for a perhaps unprecedented population crash, according to scientists and monarch watchers who have been keeping tabs on the species in their main summer home in East...
The latest survey of monarch butterflies in Mexico shows numbers are way down from last year, and the lowest since measurements began 20 years ago. Every year, the butterflies leave eastern Canada an...
